Abstract: The paper represented modeling satellite data transmission channel with cascade encoding. The detailed scheme of digital satellite data transmission channel with outer, inner encoder and interleaving was developed. The recommendation for cascade encoder components type and structure was issued. The analytical relationships and research results for describing bit error rate of the cascade turbo-encoder components were represented.
Description: The paper represents recommendations for optimizing data transmission system scheme to improve its noise immunity. The scientific novelty consists in the following statements: combining turbo-code and Reed-Solomon code of the considered configuration (TC+RS) allowed eliminating saturation effect inherent to offered TC and enhancing EEB to 8.5 dB versus unencoded QPSK, or increasing EEB at 4.8 dB versus cascade structure of CnC+interleaver+RS type. The research allows using encoding rate to optimize CnC+interleaver+RS structure. Changing encoding rate from R=3/4 to R=1/2 allowed enhancing EEB to 5.9 dB. The paper gives assessment of phase noise impact on quantity of corrected errors in the data transmission channel with cascade structure (the amount of corrected errors changed from 13 to 16 in experimental conditions) and conditions enabling to enhance EEB to 5.6 dB (R=1/2) by means of changing code structure from RS (255,247) to RS (255,223) in cascade structure.
